Preferred embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show an embodiment of a grid glass dome according to the present invention. As shown in FIG. 1, in this embodiment, the grid glass dome 1 has a hemispherical shape as a whole, A predetermined number of frame members arranged radially from the top of 1 and a predetermined number of frame members arranged concentrically around the top form a lattice-shaped roof frame. . However, the greatest feature of this embodiment is that each frame member that constitutes the roof frame as a support structure is not continuously formed as in the conventional example and does not function as a bending member, and glass. The sash member for attaching the plate is omitted.

That is, in this embodiment, as shown in FIG. 2, the lattice members 3 are formed in a lattice shape and have a length substantially equal to the length between the pair of intersections 2 and 2. , Are joined and assembled by being pin-joined at the respective intersections 2, and between the respective intersections 2 of the respective lattice members 3, tensile members 4 for reinforcement are respectively stretched and arranged diagonally. A truss is composed of the lattice members 3 as the connected aggregate and the tensile members 4. Then, for each unit space defined by the four lattice members 3 arranged in the lattice, a glass plate 5 as a roof exterior material is provided on each lattice member 3 without a sash member. It is characterized by being attached.

The lattice members 3 are connected to each other at each intersection 2 by a predetermined connecting member by so-called point joining, and the tension members 4 form a large space.
However, a cable is adopted, but in the case of a small-scale dome 1, another material that can function as a tension material such as a wire rope can be used. In addition, each tensile member 4 is arranged at a predetermined position connecting the intersections 2 and, after that, is prestressed by an appropriate device so that the tensile member 4 can sufficiently exert its function as a brace member. .

In the present embodiment having the above structure,
Compared with the conventional dome made of the truss type roof frame, the construction is much easier and the member structure is simple. That is, in the above truss type roof frame, since each truss of a triangular shape is composed of only the unit frame members, each node is pin-joined to form a hemispherical dome. It was necessary to three-dimensionally adjust the arranging direction of the frame members, etc., and the construction work was very complicated, but in comparison with this, the lattice members 3 are arranged almost orthogonally in a lattice shape. This is also because each tension member 4 need only be stretched and arranged diagonally between each intersection 2.

Further, since the trusses are formed by the lattice members 3 and the tension members 4 and the intersections 2 are pin-joined, in principle, only the axial force acts on each lattice member 3. However, in comparison with the conventional example of the above-mentioned lattice-shaped roof frame made of the bending material, each lattice material 3 may be a structural material that is remarkably light in terms of cross-sectional performance, and thus is extremely inexpensive as a whole. Can be manufactured.

Also from the viewpoint of design, the grid glass dome 1 is extremely light and has a beautiful form, since it does not require a sash member as compared with the above-mentioned conventional examples.
Can be formed.

Further, in terms of structural safety, the braces are reinforced by the tension members 4 so that sufficient yield strength is guaranteed.

The present invention is configured as described above,
The following effects can be obtained. (1) Compared with the conventional dome made of a truss type roof frame, the construction is much easier and the member structure is simple. (2) Since the truss is formed by the lattice material and the tension material and each intersection is pin-joined, in principle only axial force acts on each lattice material, and the conventional bending material Compared with the lattice-shaped roof frame according to the above, each lattice material may be a structural material that is remarkably light in terms of cross-sectional performance, and can be manufactured at a very low cost as a whole. (3) Compared with the conventional example, sash members are not required from the viewpoint of design, so the characteristics of the glass material are used to form a very light and beautifully shaped grid glass dome. Is possible. (4) In terms of structural safety, braces are reinforced by each tensile material, and sufficient proof strength is guaranteed. (5) Since each corner of the four glass plates can be point-supported,
Since the number of fixtures is small and the glass plate can be attached only by tightening bolts, construction is easy.
